From my view is hard to say under which conditions i get which one - just sometimes first one and sometimes second one. 4) It seems there are Center+LFE and Rear Left+Right jacks swapped - i had to connect Center to Rear output and vice versa. But controls in alsamixer are not swapped so i have to use Surround slider to adjust Center and LFE speakers; LFE slider to adjust Rear right speaker and finally Center slider to adjust Rear left speaker. 5) As my soundcard is 7.1, current driver is incapable to use it: [cdome@andromeda Surround-SDL-testfiles]$ speaker-test -Dsurround71 -c8 speaker-test 1.0.14rc1 Playback device is surround71 Stream parameters are 48000Hz, S16_LE, 8 channels Using 16 octaves of pink noise Channels count (8) not available for playbacks: Invalid argument Setting of hwparams failed: Invalid argument (uhm, i get that "Invalid argument" message in czech language as "Nepristupny argument", i hope that is proper translation) But as I said, it is working now (even with those minor problems)! I hope my message will help you make alsa better. Thanks again for your great work.
